The fact is that people do not talk, hear, se, touch, and taste in the ones and zeros of digital computer speak.In the above sentence, does "speak" means language? But I looked it up in the dictionary, "speak" can not be used as a noun.
Can you explain it? Thank you.
"Computer speak" means "the language of computers". You're right that "speak" on its own is not used as a noun but we sometimes add it to another word to mean "the language of XXX".
"Tech speak" means "using technical words or jargon".
